Home made old school! Glass gallon jug, crock pot filled with mineral oil, Cork in the top with a hole drilled in it, 2' of 1/4" copper tube with 1" conduit and washers silver soldered on, inlet on the bottom side, outlet on the top side. Hose from top to sink, hose on faucet to bottom inlet. Slow dribble of water to cool the coil. Did the long coiled copper tubing at first, but too much to work with and clean. You have to clean the tubing with vinegar for 20 minutes, then flush just before you start. If you clean the copper well you do not have to worry as much about getting poisoned.
Some still charcoal filter after, but that is a personal choice. There are things you watch for (blue tint, slick on the top of the liquid) so you know it is not contaminated. If the liquid "boils over", or gets in the tube you have to stop and clean everything again and start over. ALL distilled alcohol is clear. Additives or burnt oak give the color. Later outfit did 5 gal at a time. Old stainless 5 gal milk jug with the removable sealed top, but a 3/4" water cooled tube. Propane cook element to heat it SLOWLY. You can watch the vapor move up into the tube to the top of the copper. Acts like a liquid. When it starts to 'pour' over the top bend it starts the flow and the temp spikes. If it is too hot it will boil/foam up into the tube then you get to clean up and start over! Do NOT fill your vessel too full! 1/2 was usually pretty safe. Bringing back some memories. making me thirsty!
